Well other possiblities are:

look at the output of uname -a

if you get i686 you are running a 32bit kernel if the output contains
x64_64 you are running a 64 bit kernel (sometimes uname -m tells you the
same).

For Debian/*buntu: see if you can install ia32 packages. These are
compatibility packages to run 32bit binaries under 64bit systems.
Obviously those are not needed on 32bit systems and hence not available
- as far as I know.
